Each vertebra typically has several processes, including two transverse processes and one spinous process. Additionally, there are two superior articular processes and two inferior articular processes that help form joints with adjacent vertebrae. In total, a typical vertebra has five key processes, but the exact number can vary slightly depending on the specific type of vertebra (cervical, thoracic, lumbar, etc.).
The vertebra. The spine is made up of a chain of lots of smaller bones, each one of which is called a vertebra- collectively, they are known as the VERTEBRAE. The small flanges sticking out on either side of each vertebra are called PROCESSES.

There are four: one joint with the vertebra that is superior and one with the vertebra which is inferior plus superior and inferior processes (2) come off the pedicles. These articulate with the articular processes of the vertebrae above and below.

Most vertebrae have 3 processes. The spinous process, which is the one that comes straight off of your vertebral column, can actually be felt . You can feel this one particularly well at the base of your neck (this is the 7th Cervical vertebra, also known as Vertebra prominens). The very first vertebra, C1, also known at Atlas, does not have a spinous process. Each vertebra has two transverse processes which are on either side of the spinous processes. All of these processes are important for muscle attachments for movement of the head, neck and torso.
The projections that jut laterally from the sides of the vertebrae are called transverse processes. Each vertebra typically has two transverse processes, which serve as attachment points for muscles and ligaments, and help in the articulation of the vertebrae with ribs in the thoracic region.
The part of a vertebra that articulates immediately with the vertebra below it is called the inferior articular facet. This facet, located on the lower part of the vertebra's articular processes, connects with the superior articular facet of the vertebra beneath it, allowing for movement and stability in the spinal column.
The transverse processes of the first cervical vertebra (C1) are also known as the lateral masses. They are prominent bony structures that extend laterally from the sides of the vertebra and serve as points of attachment for muscles and ligaments.
There are 5 lumbar vertebra
